                                <h3>题目描述</h3><p><div>
<div>小Y来到了一个新的城市旅行。她发现了这个城市的布局是网格状的，也就是有n条从东到西的道路和m条从南到北</div>
<div>的道路，这些道路两两相交形成n&times;m个路口 (i,j)(1&le;i&le;n,1&le;j&le;m)。她发现不同的道路路况不同，所以通过不</div>
<div>同的路口需要不同的时间。通过调查发现，从路口(i,j)到路口(i,j+1)需要时间 r(i,j)，从路口(i,j)到路口(i+1</div>
<div>,j)需要时间c(i,j)。注意这里的道路是双向的。小Y有q个询问，她想知道从路口(x1,y1)到路口(x2,y2)最少需要</div>
<div>花多少时间。</div>
</div>
<p></p></p><hr/><h3>输入格式</h3><p><div>第一行包含 2 个正整数n,m，表示城市的大小。</div>
<div></div>
<div>接下来n行，每行包含m?1个整数，第i行第j个正整数表示从一个路口到另一个路口的时间r(i,j)。</div>
<div></div>
<div>接下来n?1行，每行包含m个整数，第i行第j个正整数表示从一个路口到另一个路口的时间c(i,j)。</div>
<div></div>
<div>接下来一行，包含1个正整数q，表示小Y的询问个数。</div>
<div></div>
<div>接下来q行，每行包含4个正整数 x1,y1,x2,y2，表示两个路口的位置。</div>
<p></p></p><hr/><h3>输出格式</h3><p><div>输出共q行，每行包含一个整数表示从一个路口到另一个路口最少需要花的时间。</div>
